vb.net控制鼠标位置 vbscript鼠标操作

VB.NET怎么可以限制窗体不能被鼠标随便拖动位置

很简单vb.net控制鼠标位置，通过WindowsAPIvb.net控制鼠标位置，删除窗体菜单项就行了

首先在窗体类中声明API：

Declare Function GetSystemMenu Lib "user32" (ByVal hWnd As IntPtr, ByVal bRevert As Boolean) As IntPtr

Declare Function RemoveMenu Lib "user32" (ByVal lngHmenu As IntPtr, ByVal nPosition As Integer, ByVal wFlags As Integer) As Integer

其次声明API参数常量：

Const MF_BYPOSITION As Integer = H400

然后在窗体类中写入过程：

  Private Sub UserForm_Initialize_stopmove() '禁止窗体移动

      Dim lngHwnd As IntPtr

      Dim lngHmenu As IntPtr

      lngHwnd = Me.Handle

      If lngHwnd 0 Then

          lngHmenu = GetSystemMenu(lngHwnd, False)

          RemoveMenu(lngHmenu, 0, MF_BYPOSITION) '这里的0代表菜单中从上往下数第一个菜单项

      End If

  End Sub

  Private Sub UserForm_Initialize_onmove() '恢复窗体移动

      Dim lngHwnd As IntPtr

      Dim lngHmenu As IntPtr

      lngHwnd = Me.Handle

      If lngHwnd 0 Then

          lngHmenu = GetSystemMenu(lngHwnd, True)

RemoveMenu(lngHmenu, 0, MF_BYPOSITION) '这里的0与禁止代码中的数值同步vb.net控制鼠标位置，原因时虽然表面上删除了菜单项，实则为隐藏了菜单项，各个菜单的索引值并没有变，所以0依然代表初始菜单的第一个菜单项，即被删除的那个菜单项

      End If

  End Sub

然后如果你的窗口菜单是动态变化的，建议声明常数：

Const MF_BYPOSITION As Integer = H0

然后使用相关的Windows功能的常数进行删除菜单。常数需要自行查看winuser.h头文件

如果找不到该头文件，可以看这里：网页链接

其余信息详见MSDN：网页链接

最后说一下，不建议前面网友说的重写WndProc的方法，因为这样拦截标题栏点击消息会导致窗体本身的菜单也无法显示出来，有损窗体功能，并且像双击左上角图标关闭窗体这样的功能也会跟着拦截消息的操作一起被吞掉。

如何在VB.net中用程序控制鼠标移动和点击

调用api

在Visual Baisc.net中vb.net控制鼠标位置的声明vb.net控制鼠标位置：

Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)

Public Const MOUSEEVENTF_LEFTDOWN = H2 '模拟鼠标左键按下

Public Const MOUSEEVENTF_LEFTUP = H4 ’模拟鼠标左键释放

Public Const MOUSEEVENTF_MIDDLEDOWN = H20 '模拟鼠标中间键按下

Public Const MOUSEEVENTF_MIDDLEUP = H40 '模拟鼠标中间键释放

Public Const MOUSEEVENTF_RIGHTDOWN = H8 '模拟鼠标右键按下

Public Const MOUSEEVENTF_RIGHTUP = H10 '模拟鼠标右键释放

Public Const MOUSEEVENTF_MOVE = H1 '模拟鼠标指针移动

例vb.net控制鼠标位置：

mouse_event MOUSEEVENTF_LEFTDOWN,10,10,0,0

'在（10vb.net控制鼠标位置，10）模拟鼠标左键按下

VB.NET改变鼠标位置和让鼠标消失

几乎找不到真正VB.NET的api，都是自己将VB的api改成VB.NET的api，我的理解是声明中对应输入是H的地方保留Long，其他的Long改成Integer，既然VB.NET连MSDN都找不到较全的api说明，不保证api的用法在VB.NET其他版本中适用。

给你个好玩的例子，包括鼠标的隐藏（Ctrl_↓）、显示（Ctrl_↑），移动、点击

在Form1上放上2个TextBox，其中TextBox1.Multiline = True，并且面积大些，2个Button，运行后在TextBox1中点击一下会记录位置，移开鼠标，点击移动或点击Button，可模拟在TextBox1中的点击

Public Class Form1

Public My_MousePosition As Point

'模拟鼠标移动、点击

Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Integer, ByVal dy As Integer, ByVal cButtons As Long, ByVal dwExtraInfo As Long)

'定义光标的位置

Declare Function SetCursorPos Lib "user32" Alias "SetCursorPos" (ByVal x As Integer, ByVal y As Integer) As Integer

'鼠标的隐藏

Declare Function ShowCursor Lib "user32" Alias "ShowCursor" (ByVal bShow As Integer) As Integer

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

TextBox1.Multiline = True

Button1.Text = "点击"

Button2.Text = "移动"

Me.KeyPreview = True

End Sub

Private Sub Form1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown

If e.Control And e.KeyCode = Keys.Down Then ShowCursor(0)

If e.Control And e.KeyCode = Keys.Up Then ShowCursor(1)

End Sub

Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove

TextBox2.Text = MousePosition.X " " MousePosition.Y

End Sub

Private Sub TextBox1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TextBox1.MouseClick

My_MousePosition = MousePosition

TextBox1.Text = My_MousePosition.X " " My_MousePosition.Y vbCrLf

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

SetCursorPos(My_MousePosition.X, My_MousePosition.Y)

mouse_event(H2, 0, 0, 0, 0)

mouse_event(H4, 0, 0, 0, 0)

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

SetCursorPos(My_MousePosition.X, My_MousePosition.Y)

End Sub

End Class

其中

mouse_event Lib "user32" (ByVal dwFlags As Long

的dwFlags的代码是

Const MOUSEEVENTF_LEFTDOWN = H2

Const MOUSEEVENTF_LEFTUP = H4

Const MOUSEEVENTF_MIDDLEDOWN = H20

Const MOUSEEVENTF_MIDDLEUP = H40

Const MOUSEEVENTF_MOVE = H1

Const MOUSEEVENTF_ABSOLUTE = H8000

Const MOUSEEVENTF_RIGHTDOWN = H8

Const MOUSEEVENTF_RIGHTUP = H10
